1 is a block diagram illustrating a packet network of a synchronous CDMA 2000 system to which an embodiment of the present invention is applied.

2 is a flowchart of a user status display according to an embodiment of the present invention.

The present invention relates to a mobile communication system, and more particularly, to a method for displaying a user state in a mobile communication terminal.

Patent application No. 2001-69483, filed with the Korean Intellectual Property Office, relates to a method for processing user status messages of a mobile phone. When a call signal is input from a predetermined group of phone numbers or a phone number of a specific individual, By sending a short message preset by the user, the other party who requested the call signal can know the user's status without waiting for a long time, but in this case, the user status before the other user tries to connect to the phone There is no way to know. Thus, the illustrated method has the inconvenience of trying to make at least one call connection to know the user status.

As another prior art, patent application number 2001-68085 is known. Exemplary patent application invention retrieves the list of Internet phone addresses stored in the memory and periodically receives the Internet phone information for each address from the information server and displays it to the outside, so that other Internet phones can be made without the user making a phone call. I can grasp the state of the. However, when the IP address of each Internet phone whose address is stored in the memory is changed, the status information of the IP phone whose IP is changed is not known unless the address list stored in the user's Internet phone is modified.

Therefore, it is difficult to apply the present invention to a mobile terminal in a mobile communication network using a floating IP rather than a fixed IP. In addition, by retrieving the Internet phone address list and receiving the Internet phone information for each address periodically from the information server, the same information is received even if the status information does not change, which causes a waste of communication resources. If you only want to inform your status to others and you do not want to provide your status information to other users, there is no way to support it.

Accordingly, an object of the present invention is to provide a method for displaying a state of a mobile terminal user who can know the present state of another person or provide his / her present state to another person without a call connection attempt.

Furthermore, another object of the present invention is to provide a status display method of a mobile communication terminal user, which saves communication resources by updating the status information only when the status of the terminal changes.

It is still another object of the present invention to provide a method of displaying a status of a mobile communication terminal user, which enables a third party to differentially provide his / her status information.

A method according to an embodiment of the present invention for achieving the above object is an executable method in a server that provides a status display service for mobile communication terminal users,

Receiving a SIP registration request from a mobile IP registered terminal and registering a location of the user;

Receiving SIP URL information of acquaintances from the terminal registered with the location, receiving and storing information disclosure provision grade information for each acquaintance;

Receiving the state change information of the terminal registered with the location and transmitting the state change information of the user to acquaintance terminals that want to know the state change, and transmitting only the state change information corresponding to the information disclosure providing grade information of each acquaintance; It features.

According to the characteristics of the present invention, even if acquaintances can provide their own state information differently, there is a convenience that can provide different information for each acquaintance or group.

Furthermore, the state change information of the terminal registered with the location is characterized in that it includes information indicating the call state of the other terminal.

According to this feature, since user B who has attempted to call user A can register the information as user A's status change information on the service server, user C or the like can later recognize that user A is busy. Have

Furthermore, the terminal user status display method according to another embodiment of the present invention is a method executable in the mobile communication terminal,

Transmitting a SIP registration request message to a service server;

Transmitting SIP URL information of acquaintances to the server, and setting information disclosure provision grade information for each acquaintance;

Transmitting the information to the server each time the status change information is set by the user or whenever the mail is checked; And

And receiving and displaying the state change information of the terminal registered with the location from the server.

According to the characteristics of the present invention, since the corresponding information is transmitted to the server whenever the state or user state of the terminal is changed, there is an advantage in that communication resources can be saved as compared with the existing technology.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

First, FIG. 1 is a block diagram illustrating a packet network of a synchronous CDMA 2000 system to which an embodiment of the present invention is applied. FIG. 2 is a flowchart illustrating a user status display according to an embodiment of the present invention.

Referring to FIG. 1, MSs 101 and 115, which are one of mobile communication terminals according to an embodiment of the present invention, perform call processing signaling in association with a service server 134, which will be described later, and provide a presence service based on SIP. Perform. For reference, the presence service is a service that notifies the current state (eg, on / off, Do not Disturb, Only if Urgent, etc.) of the registered contacts on the Internet. Therefore, the present invention may be called a presence service method.

On the other hand, the base transceiver station (BTS) 100, 114 is a device configured as a wireless transceiver and transmits and receives packet data with the MS (101, 115) in the radio access network (RAN) (110, 130) via a wireless link. The base station controllers 102 and 116 manage a plurality of BTSs and are responsible for radio channel setting, frequency hopping, and handover processing.

The Packet Data Serving Nodes (PDSNs) 104 and 118 operate as Foreign Agents for mobile IP services in the packet networks 112 and 128. That is, the PDSN 104,118 operates as an FA to perform agent advertisement message delivery to the MSs 101 and 115, mobile IP registration, record generation for packet accounting, PCF and R-P session establishment, PPP termination and router functions. The PDSN 104,118 initially establishes a mobile IP registration and a path with the IP network for the MS 101,115, and then the MS 101,115 interworks with the service server 134 via this path to call processing signaling. Make this exchangeable. In this case, the MSs 101 and 115 become clients of the service server 134 and exchange various signaling information for the presence service using the SIP protocol with the service server 134.

On the other hand, the home agent (HA) 106, 120 is an agent that stores information of the mobile communication user such as an IP address. Notified and provide information of the mobile communication user.

The AAA (Authentication / Authorization / Accounting) servers 108 and 122 handle authorization, authentication, and charging for users in the IP network. The AAA servers 108 and 122 manage authentication and message authentication for the mobile communication user during the initial mobile IP registration procedure for the mobile IP service, and distribute authentication key values for authentication and authorization.

The service server 134 providing the presence service performs a call exchange and call processing for buddies connected to mobile IP through the packet network 132 to support the presence service based on the SIP protocol between user terminals. Perform. More specifically, the service server 134 receives a service registration request from a mobile IP registered terminal, registers the location of the user, and receives SIP URL information of acquaintances from the terminal having registered the location, for each acquaintance. Information disclosure Provides and stores grade information. And by receiving the status change information of the terminal registered the location and transmits to the acquaintance terminals that want to know the state change of the user, by transmitting only the status change information corresponding to the information disclosure class information of each acquaintance, Each group will receive different information.

Reference numeral 136, which is not described in FIG. 1, shows the presence information DB. Presence information such as acquaintance list information of each user, status information of each acquaintance present in the list, address information of the acquaintances, contact information, etc. Is saving.

Hereinafter, a SIP-based user status display method performed in a packet network having the above-described configuration will be described in more detail.

Referring to FIG. 2, when a terminal user requests to perform a service based on a SIP-based service, the mobile communication terminal 101 sets up a traffic channel with the BSC 102 and sets up a PDPP 104 and a PPP. After notifying that the mobile IP service is to be used, the PDSN 104 performs a mobile IP registration procedure to allocate an IP address and keep the always on state by default.

Subsequently, the user A's mobile communication terminal 101 transmits a SIP registration request message to the service server 134 (S1) and receives a response. Through this step, user B and user C may also register their positions (S2, S3) in the service server 134, which is also a SIP server. In the following description, it is assumed that users A, B, and C are acquaintances who can share the presence information.

When the SIP registration is completed, User A transmits the SIP URL information of acquaintances he knows to the server 134 (S4), but sets the information disclosure providing grade information for each acquaintance and transmits them together. For reference, the SIP URL information is a value that can be stored and managed in the terminal memory. In addition, the "information disclosure rating information" is information that limits how far to disclose their information to acquaintances, the first step is a level to disclose all information, the second step is the status of the user and the terminal itself Only the status information may be disclosed, and the third step may be divided into levels that disclose only the user's status and the fourth step may be divided into levels that do not disclose the information.

In the following description, it is assumed that the user's status information is information indicating the current status of the user, such as during a meeting, during a meal, during an absence, or during bedtime. Such user status information can be set through a menu or a softkey. In addition, it is assumed that the terminal state information is information indicating an operation state of the terminal, such as whether or not a received mail is confirmed.

As described above, when SIP URL information in which information disclosure providing grade information is set for each acquaintance is transmitted from each user, the service server 134 receives the URL information and stores the URL information in the presence information DB 136.

As described above, a state in which the status information of the user A is transmitted and displayed to another user while the information on the acquaintances of the SIP registered user is stored in the server 134 will be described.

First, if the user A has set his status information to "eating, for example" through the menu (S5), the user A's terminal transmits the user status information to the server 134 in accordance with the completion of the user status information setting ( S6). Then, the server 134 stores the received state information in the presence information DB 136 (S7) and transmits the information to acquaintance terminals that want to know the state change of the user who has transmitted the information. Only state change information that meets the information disclosure grade level information is transmitted (S8, S9). For example, if user A has set user B the level of information disclosure to user B, and user C has set the level of information public offering as the second level, user B and C both have user A's status information. Since the grade can be provided, the server 134 transmits the status information of the user A to the terminal side of the user B and C.

Accordingly, user B and user C can receive the information whenever the state of user A changes.

Therefore, the present invention is not to transmit the same information to all acquaintances, it is to be able to differentially provide different information for each acquaintance or group,

The status information is updated only when the status of the terminal is changed, so that communication resources can be saved.

Meanwhile, the present invention may register the terminal state information of another person with the server 134 to propagate it to a third party. For example, if the user B attempts to call the user A, but the user A is busy, the user B may access the server 134 and change the terminal status information of the user A to the busy state (S10). This information is stored in the presence information DB 136 (S11), and is then transmitted (S12) to an acquaintance terminal that wants to know the state change of the user A, that is, the terminal of the user C.

Therefore, user C can know that user A is currently busy without calling user A.

Furthermore, information indicating whether the SIP registered user has read the received message (SMS / MMS / EMS) may be registered in the server 134 to be propagated to a third party. For example, when user A sends a short message to user C, the user A notifies the server 134 of the fact (S13). This information will be stored in the presence information DB 136 and will then be propagated to acquaintance terminals with the right to receive that information. If the user C reads the received short message, the terminal of the user C transmits a message indicating that the short message has been read to the server 134 (S14). This information is stored in the presence information DB 136 as well as propagated to the user A who sent the message (S15), so that the user A recognizes that the message he sent was read normally.

Therefore, in the present invention, even the status information of whether the acquaintance reads the received message can be known through the presence service.

As described above, the present invention can provide different status information by acquaintance or group, even if acquaintances can provide their status information differently.

Furthermore, since the present invention registers the terminal state information of another person in the server and transmits this registration information to a third party, the third party has the advantage of being able to receive its state without attempting to contact the called party. .

In addition, the present invention has the advantage of saving the communication resources compared to the existing technology because the information is transmitted and propagated to the server whenever the state or user state of the terminal changes.
